But no, because, when the focus isn't switched, there is no enter<br>
event and no keys array. The client has no idea X was pressed, so it<br>
can't possibly trigger the binding.<br>
So without the patch this is not consistent. Depending on whether the<br>
compositor binding switches the focus, the client binding works or it<br>
doesn't work.</blockquote><div><br></div><div>A problem we can solve by switching the focus. ;) I agree that it's annoying to always do this for every hotkey, so we could introduce a new wl_keyboard::leave_temporary which would inform the client that it's about to get another enter event very shortly, but shouldn't redraw itself insensitive or anything.</div><div><br></div><div>Alternately, we could bump the wl_keyboard version to just allow for consecutive enter events and never send a leave in these temporal cases.</div><div><br></div><div>For older clients, we can just send leave/enter and they can suck it up.</div><br>Either way, it makes things more predictable and allows clients to work out what's best.<div><br></div><div>Cheers,</div><div>Daniel</div>
